Hello Henri,

Alas, this bug report is of no use since it is not done with the *latest* viewer version (I cannot keep the huge symbols files for old versions, so the crash dump cannot be decoded).

Please update the report with a crash dump obtained with the current viewer version (1.26.20.46 as I am writing this) if you encounter again this crash.

Sorry, When I checked yesterday for a new version, there was none. I should have checked today since you release them so often. Which I'm not complaining mind you, one of the reasons I love this viewer! :D

I'll try to recreate the crash with the newest version.

Thanks,
Geoff

Okay, so I thought the issue was somehow fixed in the newest version, since I wasn't able to recreate the crash. However, just now, It did crash on me without any warning or error message, the viewer just vanished.

Here is the logs.

Thank you !

The crash is apparently happening whenever the viewer clears the textures download queue before leaving the departing sim. It's a race condition (something fishy happening between the viewer code, the libapr code and the OS itself) in the threading mechanism that I worked around in the past with some (seemingly) paranoid and useless checks, and I recently removed those checks (in v1.26.20.45), thinking they won't make a difference...

Well, this crash is the proof that the said checks were not at all useless neither paranoid; they will be restored in next release...

In the mean time, you may disable "Advanced" -> "Network" -> "Clear stale texture fetches on TP" to avoid such crashes.

Hello Henri,

So the new version did not fix the TP crash I was experiencing before. Still crashing after TPing.

Strange... I'll have another look, but does disabling "Advanced" -> "Network" -> "Clear stale texture fetches on TP" prevent such crashes ?

I actually haven't tried. I will as soon as I can. Which maybe to late the way you release new versions. :)

It is a different crash (a light texture pointer is not checked for NULL value before it gets unlinked from a dead object on region cleanup after TP), but that could still possibly be worked around by disabling the "Clear stale texture fetches on TP" feature.

Bug fixed for next releases.
